  • Patent number: 11103333
    Abstract: Various systems, method, and compositions for treating a tooth are disclosed herein. For example, an apparatus for treating a tooth is disclosed. The apparatus can include a chamber having an access port which places the chamber in fluid communication with a treatment region of the tooth when the chamber is coupled to tooth. A fluid motion generator can be coupled to the chamber. The fluid motion generator can be configured to direct fluid across the access port to generate fluid motion in the chamber. In various embodiments, fluid motion (e.g., vortices, swirl, etc.) can be induced at or near treatment regions of the tooth, such as a root canal or carious region.

  • Publication number: 20210106402
    Abstract: An apparatus for treating a tooth can include a fluid platform comprising a wall and a chamber at least partially defined by the wall. The fluid platform can be disposed against a tooth to retain fluid in the chamber and provide fluid communication between a treatment region of the tooth and the chamber by way of an access port. The chamber can have a central axis. A liquid supply port can be disposed to direct a liquid stream across the chamber along a stream axis non-parallel to the central axis. A suction port can be exposed to the chamber. The chamber can have a maximum lateral dimension in a plane extending substantially transverse to the central axis, the plane delimited by the wall along a boundary. A projection of the suction port onto the plane can be closer to the boundary than to the central axis of the chamber.

  • Publication number: 20210085435
    Abstract: Various apparatus and methods for cleaning teeth and gingival pockets are disclosed herein. A fluid platform can include a pressure wave generator configured to propagate pressure waves through a treatment fluid. The pressure waves may be sufficient to remove undesirable dental deposits from a treatment tooth, neighboring gums, and/or spaces between the tooth and gums.

  • Publication number: 20210068921
    Abstract: Examples of apparatus, methods, and compositions for endodontic treatments are described. The apparatus can include a fluid platform configured to substantially retain fluid in a tooth chamber during treatment. The fluid platform can help maintain fluid circulation in the tooth chamber as fluid flows into and out of the tooth chamber. The apparatus can also include a pressure wave generator configured to generate acoustic waves that can be used for cleaning root canals and tooth surfaces in the tooth chamber. Examples of pressure wave generators include a liquid jet, an electromagnetic energy delivery device, and an ultrasonic device. The fluid can include antiseptic or antibacterial solutions to assist in tooth cleaning. The fluid may be degassed to have a reduced dissolved gas content (compared to non-degassed fluids used in endodontic treatments), which may improve the effectiveness of the pressure wave generation or the cleaning.

  • Patent number: 10806544
    Abstract: In some embodiments, a method for removing a foreign object from a root canal of a tooth is disclosed. The method can include positioning a fluid generator to be in fluid communication with the root canal of the tooth. Fluid can be supplied to the root canal. The method can include generating fluid motion and/or pressure waves in the fluid in the root canal with the fluid motion generator. The foreign object can be removed from the root canal with the pressure waves and/or the fluid motion.

  • Publication number: 20200297455
    Abstract: A dental treatment system can include a console, a tooth coupler, and an interface member that provides at least one of fluidic, electrical, mechanical, and data communication between the tooth coupler and the console. The tooth coupler (which may comprise a handpiece or a treatment cap) can act as a working end of the system to administer a suitable treatment procedure, such as a cleaning procedure, an obturation procedure, a restoration procedure, etc. The tooth coupler can removably engage the interface member such that the clinician can easily engage and disengage the tooth coupler and interface member.

  • Publication number: 20200146774
    Abstract: Systems and methods for using a liquid jet apparatus for dental treatments are disclosed. In one implementation, the liquid jet apparatus may include a handpiece configured to deliver a high velocity liquid jet to a desired location in the mouth of a patient. The handpiece may include a positioning member having a channel through or along which the jet can propagate. The positioning member may have a distal end portion configured to be at least partially disposed in a pulp cavity, canal space, or opening in the tooth under treatment. During operation, the jet may impact an impingement surface of the distal end portion of the positioning member and be deflected as a spray through one or more openings in the distal end portion. The liquid jet apparatus may be used for root canal treatments.
